To all whom it may concern:

Be it known thatI, I'IIRAM A. Foss, a citizen of the United States,residing int-"Albion, in the county of Kennebec and State of Maine, haveinvented new and useful Ink provements in Light-Projecting Attachmentsfor Firearms, of which the following is a specification.

. his invention relates to an attachment for firearms, whereby thelatter can be used 1 for accurate shooting by night, there being a rayof light directed on the object aimed at.

The invention has for one of its objects toimprove and simplify theconstruction of devices of this character so as to beeompara:

tively simple and inexpensiveto manufacture, reliable and efficient in'use, and so designed as to be readil removed therefrom. v

Another object of the invention is the provision of a light-projectingdevice consisting of tube of telescopically arranged sections and novelmeans for attaching the ends of the tube, when extended, to the barrelof the firearm.

\Vith these objects in view and others, as will appear as thedescription proceeds, the

invention comprises the various novel features of construction. andarrangement of parts XVlllCh wlll be more fully described.

ereinafter and set forth with particularity;

in the claims appended hereto.

In the acconi anying drawing, which illustrates one em odiment of theinvention,

Figure 1 is a side 'view of the device ap )lied to a rifle. Fig. 2 1s acentral longitu lnal section of the device with an intermediate portionof the tube broken away Fig. 3 is aperspective view of-the rearattaching means for the tube. Fig. 4 is a pers ective view of the frontattaching means. ig. 5 is a persp ective view of'the light retainer.

Similar reference characters are employed to designate correspondingparts throughout the gun, the tube. is preferably made in sec- 37applied to a firearm or tions-a which telescope one within another.lnthe front end ofthe tube is a plug 2 having a light-eihitting opening3. ger end'ofthe tube. is a suitable light such as In the rear lar a a-11 an incandescent lamp 1 connected with a battery 5 removablyj mountedin the tube and held thereinjbyz, retainer 6 hingedlyl connected with;the rear end of the tubeto 1 extend across the outer end of thebattery.]

When I the device is used, the tube is ex -Q tended by pulling out thesuccessive sec tionsto the position shown in Fig. 1, and the 1 it endsofthe tube areattached to 'the'b'arrel. 61

Oftherifle.

The front end of the. tube is attached to the rifle barrel b sight 8 onthe rifle barrel The rifle sight com rises a dove-tail base 9 formedwith a stu 10 rising therefrom which has an open the attaching means. ishown in IFig. 4,'w1ieh"means consists of a bandor ring 7 embracing thefront section of the tube and suitably secured to the front sight notch11 in its top and a transverse aperture 12. The ring 7 is formed withspaced ears 13 for engaging op osite sides of the stud 10 and a bolt orastening screw 14 passes through the apertures 12 and 15 of l 1 the studand ring, respectively. The screw 14 constitutes a pivot for-permittingthe rear end of the tube to be raised or lowered to adapt the device fordifferent ranges. Whenthe light projecting device is not in use, thefastening ring 7 canbe thrown down against the barrel of the rifle to beout of the way, and the sight 11: can be used in the usual manner. Thebase 9 of the front sight is set into a dove-tail transverse slot 16inthe rifle barrel, as shown in Fig. 1.

The means for attaching the rear end of the tube-to the rifle. barrelconsists of a spring 17 attached to-adove-tail base piece which is heldin av correspondingly-shaped transverse groove 19 in the rifle barrel atthe it i rear end thereof. On; the free end of" the spring is ahingedly-connected pawl 20 which is adapted toenga 'e in an one of a"series of" notches 21 on the barre whereby the spring can be raised orlowered for changing the ra e of the sighting device, there bein a noteor peep sight 22 for use in connection withthe frontfsight when shootingin the daytime, Therear end of the tube is adapted to be connectedwiththe rear sighting device by a U-shaped clamping spring '23 detachablyconnected by'a screw or equivalent means 24 to the spring 17.

. It will thus beseen that by; adjusting the I Froject device, means forattaching the 25 spring, the light-projectingw%ev1ce can be ront on ofthe device to the rifle, and set for any given range. en the light-'means for attac the rear end of the deprojecting device is not to beused in 'convice to the rear sig ,t for adjustment there- 6 nectionwith'the gun, the spring 23 can be with.
